I have to say that I *LOVE* Picasa. I have been using it ever since it was acquired by Google. I love all of the features it had in the beginning and then with the release of Version 2, I loved it even more.
I have a suggestion for the person who called in about Picasa today. Make backup discs with Picasa. Don't worry, you will always have access to your original images, it stores the images on the CD/DVD that you burned it to. You don't need Picasa to pull the images back off of the CD/DVD. If for some reason Google decides they don't want to continue with Picasa, then you will at least have the backups of the originals.
Also, I put all of my images into a dated folder. If you don't make any changes to your EXIF data, then most programs will be able to sort your images by the date you took them.
If you have Linux, there is a great program called FSpot that does a lot of the same things that Picasa does...but not everything. DigiKam is also pretty good.
One of the best French door fridges we've tested
A good-looking fridge with useful features like an auto-filling water pitcher and a temperature-adjustable "FlexZone" drawer. It was a near-flawless performer in our cooling tests.
